Patented Dec. 4, 1934 UNITED STATES PATENT; omen HAIR WAVERi Fritz Binder, Kansas ammo, Application July 17, 1933, Seria1No. 680,806 I 9 Claims. (01.. 132-33) t This invention relates to hair waving apparatus and particularly that member of such equipment upon, which is wound strands of hair to be curled and which also supports the wound strand of hair during the time heat is being applied thereto.

The primary object of this invention is the contemplation of an especially efficient, simple and durable part having members which insulate the body of the apparatus from transmitting heat to the scalp and head and which maintain the spool receiving the strands of hair in a position against rotation until longitudinal movement is imparted thereto, such elements being constructed in a special manner as will hereinafter be fully set forth. 1

With these general objects in view and such structural features as constitute minor objects in mind, the invention will be fully described by reference to the accompanying drawing, wherein:

Figure 1 is .a vertical, longitudinal, substantiallyv central section through a hair waving unit embodying this invention.

Fig. 2 is a top plan view of the same, with parts broken away forclearness.

Fig.3 is an end elevation of the unit.

Fig. 4 is an end elevation of the unit illustrating the opposite end from that shown in Fig. 3, and,

Fig. 5 is a vertical, central cross section taken on line VV of Fig. 1.

Like reference characters will be used to designate similar parts throughout the I several views, and the numeral 8 indicates a body formed of metal and having an upturned end portion to form a bearing 10 at one end of body 8, and a bearing 12 at the other end thereof.

The base portion 14 of body 8 which extends between bearings 10 and 12 is'both longitudinally and transversely arched as illustrated in Figs.

1 and 4 respectively. Since body 8 is made from sheet metal, it is preferable to blank the same in a manner which will permit forming base 14 from two thicknesses of the sheet metal from which body 8 is formed. In so forming the base 14 of body 8, laminations as shown in Fig. 1 assist in precluding any warping that might take place as th result of the application of heat when the hair curling unit is in operation. Each of bearings 10 and 12 respectively has a slot 16 and 18 respectively formed therein to receive shafts 20 and 22 respectively in the manner hereinafter set down.

The curved face of base 14 lies adjacent the scalp when the hair is being curled and since practice requires that heat be applied, this invention has contemplated the use of an insu'a lating face plate 24which is made of fiber, wood,. composition material, or any other substance which will suitably preclude transmission of heat to the scalp. The bearing face 26 of insulating face plate; 24 is likewise arched both longitudinally and transversely and this plate is held in operative position by a series of dove-tailed lugs 28 formedintegrally, and removably projecting into grooves 30 formed in the lowermost lamination of base 14. p v

As shownin Fig. 2, these grooves do not pass entirely across lowermost lamination of base 14 and therefore insulating face plate 24'may be moved into place from one side of base 14 only. This manner of constructing and bringing together the parts not only precludes transverse. sliding of plate 24,: but permitsblanking out and forming the body and slots 8 and 30 respectively in an economical manner.

As is shown in. the drawing, and especially Fig. 1, plate 24 is held in spaced relation to the lowermost faceof base 14. This air space 32 allows free circulation to break down any tendency of heat to pass from body 8 toward the scalp. Spool 34 is pivotally mounted in bearings 10 and 12 respectively and thepintles 20 and 22 are formed in a manner to create a key 36 and head 38 respectively. A clamp .40, pivotally mounted as at 42, is utilized to retain the endsof the strands of hair in place as spool 34 is. being rotated, but since head 38 is squared, to be engaged by the two parallel sides of slot 18 formed by hearing 12, spool 34 must be held in a position where slot and head 18 and 38 respectively are out of engagement beforerotationcantake place. The force holding spool 34 in a rotatable position must be suflicient to overcome the urgeof spring 44 which establishes a. constant pressure against spool 34 to move it against bearing 10 and to hold head 38111 a locked position.

Spring ,44. is wound about pintle 22 and extends against member 46 integral with pintle 22. and within spool 34. A complementary member 48 is rigidly secured in position within spool 34 and teeth 50 and 52 formed on members 46 and 4a. res pectivelyestablish a ratchetwhereby the against body 8 by some suitable means duringthe use of this unit and to carry out this requirement, one edge or" base 14 is providedwith a resilient strip 56. Against this resilient strip 56 is swung a resilient clamping jaw 58 and the abutting, longitudinal, arched faces of members 56 and 58 are formed as shown in Fig. 5 to present longitudinal serrations or grooves which establish a much tighter connection between the two when the members are in the clamping position than would otherwise occur.

Member 58 is of rubber or other resilient material and is threaded upon a laminated strip 60, one end of which is hingedly mounted as at 62 to body 8. The other end of strip is engaged by a clamping lock such as is well known in the art and which comprises a link 64 and trigger 66, one end of which has a cam formed thereon to bear against the extended end of strip 60. This means of securing a clamping jaw in place is very well known in this art and further explanation is deemed unnecessary.

To preclude warping and to maintain the arched rigidity which is necessary, strip 60 is made of two pieces of material, one U-shaped in transverse cross section and the other embraced by said U-shaped member. These members 68 and 70 are clearly shown in Fig. 5.

The operation of this hair waving apparatus has been made clear during the course of the specification, and while many changes as to specific structure might be made without departing from the spirit of the invention, it is desired to be limited only by the scope of the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is: r

1. Hair waving apparatus comprising a spoolsupporting body having a base and integral upturned ends forming bearings; and a spool, having its annular side arched longitudinally, rotatably carried by the said bearings; said base being arched longitudinally and concentrically with the arched annular side of the spool whereby the distance between spool side and base remains the same throughout the length of the spool as the latter is rotated upon its longitudinal axis.

2. Hair waving apparatus comprising a spoolsupporting body having a base and integral up turned ends forming bearings; and a spool taper- 65 ing from its ends toward its center rotatably carried byv the saidbearings, said base being longi-' tudinally arched concentrically with the taper of said spool and arched transversely whereby to turned ends forming bearings; a spool rotatably carried by the said bearings; pintles on the spool journalled in the bearings; a head formed on one of said pintles; and a resilient member interposed between one of said bearings and the adjacent end of the spool whereby to urge the said spool longitudinally toward the other bearing and to maintain the said head within the bearing adjacent the spring.

5. In a hair waving apparatus of the type de scribed, a base; a hair receiving spool rotatably mounted on the base; and a longitudinally and transversely arched insulating face-plate supported in spaced relation to the said base.
